The Tetra Filter Foam BF800/BF1000 Plus is specifically designed for use with Tetratec IN 800 and IN 1000 Plus internal filters. This foam serves as the primary filtration media, capturing medium to large particles while providing a surface for beneficial bacteria to grow. These bacteria help break down harmful ammonia and nitrite, promoting a healthy aquarium environment. Please note, this replacement foam is compatible only with the Tetratec IN 800 and IN 1000 Plus models.
